Shields, of which the following is a speciication.

This invention is a novel construction of` wind shield for automobiles 'and similar` vehicles, the object of the invention beingI to provide a wind shield embodying upper and lower protecting panels, said panels being adjustable both in unison and also independently of each other.

Another object ot' the invention is to .provide a wind shield of this character in which a multiplicity of adjustments can be had.

Another object oi the invention is to so conm'uct and arrange the various parts that they will be held securely in their various adjusted positions, of th'e parts falling or dropping out of position during the adjustment or fastening of any other part.

lAnother object of the invention to provide a novel method of securing the glass panel rigidly withinthe trame and preventing any possible looseness and rattling taking place between the glass panel and frame for the same.

Another object of the invention is to provide a vent at the bottom of the wind shield whereby excessive heat in the fore'part of the car can be relieved, and a still further object of the invention is to providea novel constrction of, fastening device for conmeeting the wind shield to the automobile.

With these objects in View and with eertain other objects as will appear hereinafter my invention consists in the novel features of construction, combination and arrangement of `parts all ot which will be fully described and pointed out in the claims.

In the drawings forming a part of this specification: Figure 1 is a rear view of a wind shield constructed in accordance with my invention. Fig. 2 is a vertical sectional vie'w showing the connection between the upper and lower frames and panels. Fig. 3 is a detail sectional view on the line 3-3 oi Fig. 1. Fig'. 4 is a detail sectional view on the line fr-4. of Fig. l. Fig. 5 is a side elevation of the wind shield,.the various adjustments of the frames and panels being the lower pane ble division takes thereby 'preventing anyA indicated in dotted lines. Fig. 6 is Aan enlarged detail sectional view taken on the line 6--6 of Fig. A1'. Fig. 7 is an enlarged detail perspective view ofV the flat faced enlargement lupon the side of the upper :trame and, Fig. 8 is an enlarged detail perspective view illustratin' the nanner Uf connecting the free end o the glass panel to its trarne. i

'in the practical embodiment 'of my invention, I employ a lower trame A and an upper `frame said frames constituting when lconnected a rectangle and each frame carries a glass anel A2, the upper edge 'of being free and the lower edge oi' the upper panel being free s that when the two panels meet the smallest pos'siplace, thereby providing a complete transparent shield, the vision not beinintefrruptedby any intersection 'cross mem ers -carried by the upper and lower edges res ectively of the glass panels. In practice prefer to construlct the frames A. and A of tubing to which is connected a channeled stril in which rests the led e of the glass pane, 'any suitable cement eing employed to secure the glass within the channeled strip.

The lower frame A is pivotally connected to castings B, by means of lclips B. Thfe castings B are tadapted to be attached to the opposite ends of the 'filler b'or'd 13"', said castings being made hollow as shown to receive the end of theiller board and having their outery portions extiendina considerable distance so as to firmly em race the end of said filler board as most clearly shown in Figs. 1i and 5. Between the lower end of the lowe'r frame and the filler board, I arrange a sunplemental frame C having 'a glass panel said framebeing pivotally connected to the ltubin f of the lower lframe b'y means of clips (32,11 d this supplemental frame C is of such size and shape as te lit snugly between the frame and {iller board and end castings and is ada t'ed to swing inwardly andvupwardly, a suitable handle being provided. In automobiles in which the forepart thereof is inclosed, it often oc'curs that the orepart' of the car becomes very warm and in order to ventilate the forepart of the car and still maintain a protective wind shield, I provide this supplemental inwardly and upwardly swinging frame, which is preferably provided with a glass panel, but it will of course be understood that it is not absolutely necessary that this panelbe transparent although it adds materially'to the efficiency of the shield as a whole, to have the same transparent.

The lower frame A is provided at its opposite upper .ends with disks D, each disk having a plvot pin or screw D and binding pin or screw D2, nuts D3 and spring washers D4 being arranged upon the pivot pins.

E-E indicate arms which serve to connect the upper and lower frames, said arms having disk-like enlargements E at their upper and lower ends, and each disk-like enlargement is provided with a pivot hole E2 through which the pivot pins D pass, and in addition to the pivot hole E2, each disk-like enlargement is provided with a concentric slot E3 and in which the binding pin or screw works, -a hand nut F being screwed upon the screw D2 and serving to rigidly bind the disk D and lower enlargements E together, a suitable washer F being interposed, and in practice l prefer to make this washer F in the .form of a casting which carries a split collar F 2 into which is fitted the upper end of the tubular brace rod F3, said tubular brace rod being preferably constructed in telescopic sections so as to compensate for the adjustments hereinafter described and are locked in their adjusted positions through the medium of a rod Ft and divided nut, (not shown).

Broad flat faced bearings G are provided upon the opposite sides of the upper frame adjacent the center of said sides, each broad (ft/ced bearing having a pivot pin or screw passing throughthe pivot hole E2, while the binding screw works in the concentric slot E3 which is produced in the disk-like enlargement E but in reverse order as most clearly shown in F ig. 5, and the hand nut is screwed upon the binding screw, suitable washers being interposed and preferably made conical as shown. Nuts D3 and spring washers D4 are fastened upon the pivot pins or screws G', and sulicient tension can be placed upon these spring washers'to bind the parts together under normal conditions and this connection between the disk D, broad fiat bearings G and the disk like en largements E will be suiiicient to hold the upper and lower frames in their adjusted positions under normal conditions until they can be securely locked by the independent locking means, namely the binding hand nutsl F. By this it will be understood that during any adjustment or manipulation during which the binding nuts are released, the action of the tension nuts and spring washers will be sufficient to maintain the parts in their normal positions thereby preventing the upper frame or any of the parts dropping down or becomingv misplaced.

and a binding screw G2, the pivot pin.

vwardly or rearwardly.

The desired adjustment can then be completed and the parts securely locked by turning up the binding nuts F.

By means of a wind shield constructed and it is obvious that a multiplicity of adjustm ments can be had. s t

If desired the wind shield comprislng the upper and lower frames and panels can be maintained either in a vertical position, or inclined forwardly or rearwardly as desired. Furthermore the lower frame can be 4mamtained in aivertical position and the upper 'rame turned to either a horizontal posltion or a forwardly or rearwardly inclined position, and in addition to these adjustments it is obvious that the lower frame can be inclined either forwardly or rearwardly and at the same time and independent thereof the upper frame can be inclined either for- During these various adjustments the upper frame and the arms turn upon the pivot ins or screws, the bindingscrews working reely in the concentric slots, and when the parts are locked together the binding nut transmits its force to the washer which of course is of such size as to extend as to bind the `disk like enlargements of the arms to the surface carried by the upper frame.Y l

In view of the fact that there is no intersecting cross strip the view through .the shield will be absolutely unobstructed.

The upper and lower frames being open rectangles, l deem it advisable to provide a connection between the glass panels andthe upper and lower ends respectively oi" the lower and upper frames so as to prevent any possible looseness at this point and this .l accomplish by reducing each panel slightly for a short distance at each end, said reduction being indicated at l and at the inner end of each reduced portion I provide a recess or notch or opening I and resting within or upon the reduced portion the small metal bar K having a protuberance 2 at its inner end, which is of a size and shape adapted to lit in the recessv or notch l.

Downwardly extending brace portions K4 are rigidlyV connected to the bars K and sides of the frame upon opposite sides of the glass panel as most clearly shown in Figs. 1,' 2

and 8-,and these braces are brazed or otherwise connected to the parts so as to provide an absolutely rigid connection and it will be noted that the edge of the bar is flush with the edge, of the panel and in turning the frame and panels back and forth upon their pivots these metallic bars will receive whatever strain or pressure is exerted at these points and thereby save the edges. of the gllass panels from grinding one` upon the ot ier.

arranged as herein shown and described` across the concentric groove sodisk and the broad flat bearing lin practice ,llL prefer to employ a cushion 13@ modifications can be made in the features of construction and arrangement without departing from the fundamental principles of my invention.

What I claim is.-

1. In a wind shield, the combination with .the upper and lower frames, of a fillerboard and end castings, the lower fframe being pivotally connected to said castings and a supplemental frame pivoted t0, Said lower frame and adapted to occupy the space between the filler-board, castings and lower frame as set forth.

2. In a wind shield the combination with' a filler-board and castings of a wind shield frame pivotally connected to said castings and a supplemental frame arranged between the castings and pivotally connected to the Wind shield frame, said supplemental frame having a panel and being adapted to open and close the space between the filler-board and frame as set forth.
